ADJUSTABLE DIE-HOLDER FOR WIRE-DRAWING MACHINES.

,SPECIFIGATION forming part of Letters Patent No. 662,271, dated November 20, 1900. Application filed Jtme 18,1900 Serial No. 20,707; (No model.)

To aZZ 1071,0171, it may concern.-

Be it known that I, JOHN W. HAWKINS, a citizen of the United States, residing at Guyahoga Falls, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Adjustable Die-Holders for Tire-Drawing Machines, of which the following is a specification.

My invention has relation to improvements in die-holders for wire-drawing machines; and one object of my invention is to enable the die to be raised or lowered to bring the opening in the die near the horizontal line of the drawing-spool, especially when the die has two or more openings in vertical alinement, and a further object is to tilt or incline the die, so that it will be exactly transverse to the line of draft.

To the aforesaid objects my invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter described and then specifically pointed out in the claims, reference being had to the accompanying drawings, forming a part of this specification. i

In the accompanying drawings, in which similar reference-numerals indicate like parts in the different figures, Figure 1 is a side elevation; Fig. 2, a plan, and Fig. 3 a front elevation.

Referring to the figures, 1 is a bed-plate or base with the central part cut away, leaving two projecting ends 2 2, curved upward and backward, forming hooks and having vertical side wings 3 3. Two fiat bars 4 4: are bent to form three sides of a parallelogram, with one.

end longer than the other, and these longer ends are bent to enter and be retained in the hooked ends 2 2 by pivots 5 5, which pass through angle-plates 6 6, that in turn hold the longer ends of the bars 4 4 against lateral displacement. The bars 4 4 are united at the top by a cross-bar or bridge 7, secured by rivets 8, in which bridge is a screw-threaded opening in which runs a hollow bolt 9, also internally screw-threaded to receive a bolt 10. The lower end of the bolt 9 is reduced and screw-threaded and carries a nut 11.

Mounted to slide vertically between the depending ends of the bars 4. 4, which constitute ways or guides for the purpose, is the die-holding frame 12, which consists of a wide fiat bar bent into a parallelogram; with its upper ends overlapping and perforated to re ceive the reduced screw-threaded end of the bolt 9 and to be secured thereon by the nut 11. The frame 12 has slotted openings 13 at front and back in horizontal alineme'nt. At the back end of the bed-plate l is secured a plate 14:, its outer end bent up at an angle of about forty-five degrees. The upper end of the bent portion of the plate 14 has a hole in which is a screw-threaded rod 15, adjustably retained by nuts 16 17. The opposite end of the rod 15 is forked and the ends bent and hooked into holes in the bars 4 4.. The die 18 is of the usual pattern and consists of a steel bar perforated at determined intervals with conical holes, one of which 19 is shown in Fig. 1. This bar may be of any length, the illustration showing it broken at each end, and the holes will be of various sizes and usually arranged in horizontal and vertical rank.

The apparatus is pivotally connected with the wire-drawing bench by a bolt that passes through a hole 20 in the plate 1, thus permitting the front part of the machine a lateral movement to adapt it to the line of draft of the wire.

In operation the die is placed in the frame 12 and secured by turning the screw 10 firmly against it. By turning the bolt 9 the frame 12 and die 18 can be raised to any desired height within the compass of the machine, and the angle of the frame 12 and die can be regulated by the nuts 16 17, thus enabling the operator to secure both the proper elevation of the die and the exact angle to have the wire draw at a right angle to the face of the die.

I claim as my invention 1. An adjustable die-holder for wire-drawing machines embodying a base or bed, with means for pivotally connecting it with the drawing-bench, vertical guides to receive a die-frame arranged to be rocked to and from thewire-drawingspool, means for rockingand retaining said guides at any desired angle, a die-frame arranged to move in said guides, a screw to adjust the height of said die-frame, and means for looking a die therein, all constructed and arranged substantially as shown and described.

2. The herein-described die-holder for wiredrawing machines consisting of a base or bed, with upward-turned hooks at the front and lateral wings and a raised portion at the back to receive an adjusting-screw, in combination with parallel guides arranged to be secured in said hooks, a bridge to unite said guides, a bolt resting in an opening in the raised portion of said base, connected with said guides and provided with adjusting-nuts to rock said guides, a die-holding frame arranged to move vertically in said guides, a hollow screwthreaded bolt to raise and lower said frame and an internal screw-threaded bolt to secure the die therein, all constructed substantially as shown and described.

.3. An improved die-holder for wire-drawing machines consisting of a base or bed with means for pivotall-y connecting parallel guides therewith, parallel guides pivotally connected with said bed, a yoke to connect said guides, a forked brace to regulate the angle of said guides, and provided with means for adjustably securing it to said base, a dieholding frame arranged to move in said guides, with means for moving it and means for securing said die in said frame, substantially screw-threaded bolt within said hollow bolt to lock the die in the frame, substantially as shown and described.

In testimony that I claim the above I hereunto set my hand in the presence of two subscribing witnesses.

JOHN W. HAWKINS.
